[0003] However, traditional artificial surface attachment methods have low attachment efficiency and poor attachment quality when faced with such highly complex, highly curvature-varying, or irregular surfaces containing tiny feature areas (such as edges, corners, and concave-convex structures). Summary of the Invention

[0004] The main purpose of the present invention is to provide a flat material shaping mechanism and processing equipment, aiming to improve the attachment efficiency and thus enhance the attachment quality.

[0012] In one embodiment, the flat material shaping mechanism further includes a positioning component, which is mounted on a slider of the linear module and spaced apart from the forming component for pre-positioning the flat material before forming.

[0013] In one embodiment, the positioning assembly includes:

[0014] A positioning platform, the positioning platform is mounted on the slider of the linear module;

[0015] and at least two side pushers, wherein the two side pushers are mounted on the positioning platform and located on both sides of the positioning platform for defining two sides of the leveling material.

[0016] In one embodiment, each of the side pushing members comprises:

[0017] A side thrust cylinder, the side thrust cylinder being mounted on the positioning platform;

[0018] an elastic member, one end of which is connected to the telescopic rod of the side thrust cylinder;

[0019] and a push head connected to the other end of the elastic member so that the push head can move relative to the side thrust cylinder.

[0020] In one embodiment, a flexible portion is provided on a side of the pusher head facing away from the elastic member, and the flexible portion is used to contact and level the material.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0039] In existing technologies, precision manufacturing often requires attaching sheet-like functional materials to irregularly curved substrates. Traditional manual attachment methods rely on operator experience, making it difficult to maintain efficient and precise attachment on complex surfaces with large curvature variations or areas containing tiny features. This is particularly true in the manufacture of optical electronic devices, where decorative and protective layers must closely conform to the curved surfaces of temples or frames. Manual handling can easily create bubbles or wrinkles, leading to degraded optical performance and reduced product yields.

[0040] To address these issues, researchers observed that existing attachment devices are only suitable for flat or simply curved surfaces and are unable to adapt to highly complex and irregularly shaped surfaces. Analyzing the material forming mechanism, they discovered that rigid support and dynamic positioning are key factors in ensuring attachment accuracy. Consequently, they proposed combining the forming assembly with a linear motion mechanism, achieving adaptive forming of diverse material shapes through a modular design.

[0041] Therefore, see Figure 1 and Figure 2 The present application proposes a flat material shaping mechanism, which includes a linear module 10 and at least one forming assembly 20. The forming assembly 20 includes a forming block 21 mounted on a slider of the linear module 10 and a forming workpiece 22. The forming workpiece 22 is disposed adjacent to the forming block 21 and is used to attach the flat material to the forming block 21 so that the flat material is closely formed to the contour of the forming block 21.

[0042] The linear module 10 is a mechanical transmission device with high-precision linear displacement capabilities, which can be implemented using a ball screw drive or a synchronous belt drive structure, and is used to drive the forming assembly 20 along a predetermined trajectory. The forming block 21 is a rigid support body with a target forming profile, which can be formed by processing aluminum alloy or engineering plastics, and its surface profile matches the special-shaped curved surface of the substrate to be bonded. The forming workpiece 22 is an auxiliary forming device that acts on the flat material and is used to generate a restraining force to make the material adhere to the forming block 21. The forming block 21 is detachably mounted on the slider. The flat material is a graphite sheet or a heat sink.

[0043] The contour of the molding surface 21 b of the molding block 21 matches the curved contour of the target area of ​​the special-shaped shell substrate to be attached.

[0044] Specifically, the linear module 10 uses a slider to move the forming assembly 20 to a preset position. The forming element 22 activates and applies force to the flattened material, securing it to the surface of the forming block 21 and conforming perfectly to its contours. The three-dimensional curved surface of the forming block 21 maintains the material's shape through rigid support. The linear module 10 adjusts the position of the forming assembly 20 to accommodate materials or substrates of varying sizes. Once the material is formed, it is transferred to the target substrate by a matching robotic arm for attachment.

[0045] Compared to existing technologies, traditional manual attachment relies on operator experience and cannot guarantee surface fit and repeatability. This solution, through the combination of a rigid forming block 21 and a linear module 10, achieves mechanical positioning and automated control during the material pre-forming process, eliminating deformation errors caused by manual operation. The synergistic effect of the forming workpiece 22 and the forming block 21 allows the material to form a three-dimensional shape that matches the target substrate before transfer, significantly reducing the difficulty of subsequent adjustments in the attachment process, thereby improving attachment efficiency and ultimately, enhancing attachment quality.

[0046] This application effectively solves the wrinkle and bubble issues associated with attaching irregularly shaped surfaces, improving the precision of the bonding between optical films and complex substrates. The three-dimensional contour replication function of the forming block 21 ensures that the material form is highly consistent with the target curved surface, while the adjustability of the linear module 10 supports rapid production switching between multiple material types. This flattened material shaping mechanism is particularly suitable for automated placement of small, irregularly shaped components such as AR glasses temples, significantly improving production yield and efficiency.

[0047] See also Figure 1 and Figure 2 The present application further proposes that the forming block 21 is provided with at least one suction hole 21a, and the forming workpiece 22 is a vacuum generator, which is connected to the suction hole 21a and is used to allow the suction hole 21a on the forming block 21 to generate negative pressure so that the flat material is attached to the forming block 21.

[0048] The suction hole 21a refers to a through-hole formed on the surface of the forming block 21, which is used to flatten the material by adsorbing it through negative pressure. Specifically, this can be achieved using a microporous array, and its function is to evenly adhere the material through negative pressure distribution. The vacuum generator refers to a pneumatic component that can generate negative pressure. Specifically, it can be achieved using a Venturi tube structure or a vacuum pump. A closed air path is formed with the suction hole 21a through a connecting pipe, thereby forming a stable adsorption force at the suction hole 21a. The suction hole 21a is connected to the vacuum generator through a connecting pipe provided in the forming block 21, and the connecting pipe forms a branch network inside the forming block 21.

[0049] Specifically, suction holes 21a are located within the forming block 21. When the vacuum generator is activated, a negative pressure zone is created at these holes, drawing the flattened material onto the surface of the forming block 21, where it adheres closely to its contours. The negative pressure is distributed across the entire forming surface 21b through the evenly spaced suction holes 21a, ensuring that the flattened material does not become loose or wrinkled. During this process, the vacuum generator adjusts the negative pressure intensity to accommodate different flattened materials, such as optical films or flexible circuits.

[0050] Compared to existing technologies, traditional manual attachment relies on operator experience and force, which can easily lead to material stretching and deformation or loose adhesion due to uneven force application, while mechanical pressing devices are difficult to adapt to complex curved surfaces. This solution uses vacuum adsorption to achieve automated and uniform negative pressure distribution, allowing materials to precisely adhere to irregular curved surfaces without manual intervention. It is particularly suitable for shell surfaces with small features.

[0051] Through the above technical solution, the present application solves the problem that flat materials are prone to bubbles, wrinkles or partial detachment when attached to complex curved surfaces, ensures that the material fits precisely with the contour of the forming block 21, avoids unstable attachment quality due to manual operation errors, and improves attachment efficiency.

[0052] See also Figure 1 and Figure 2 The present application further proposes that the forming block 21 has a forming surface 21b, which is a surface for attaching a flat material; the forming surface 21b is provided with a plurality of suction holes 21a, and the plurality of suction holes 21a are evenly distributed.

[0053] The forming surface 21b refers to the surface area of ​​the forming block 21 that directly contacts the flat material. The forming surface 21b can be a flat surface, a curved surface, or a composite geometric shape, with its contour matching the three-dimensional structure of the target product. Uniform distribution of the air intake holes 21a refers to the arrangement of multiple holes in the forming surface 21b region at predetermined or irregular spacing. Specifically, this can be achieved using a matrix arrangement, a concentric circle arrangement, or an evenly spaced or unevenly spaced arrangement along the normal direction of the curved surface. Uniform coverage is achieved by maintaining consistent spacing between adjacent holes.

[0054] Specifically, the forming surface 21b is configured as a contoured curved surface that matches the surface morphology of the irregular shell substrate. The suction holes 21a are evenly distributed across this contoured surface. When the vacuum generator is activated, negative pressure is applied to the flat material surface through the evenly distributed suction holes 21a, ensuring balanced suction force across areas of varying curvature, edge transitions, and subtle features. For example, negative pressure is simultaneously applied to both raised and recessed areas of the curved surface, preventing the material from detaching from the forming surface 21b or creating wrinkles due to insufficient localized suction force. For irregularly shaped surfaces with sharp inflections, the suction holes 21a are symmetrically distributed along the inflection line to ensure simultaneous material adhesion on both sides.

[0055] The evenly distributed suction holes 21a of the present application make the negative pressure intensity of each area of ​​the forming surface 21b tend to be consistent, especially for the area with sudden change in curvature. By increasing the hole density per unit area to compensate for the attenuation of adsorption force caused by the curved surface morphology, it can eliminate bubbles, wrinkles or edge lift caused by insufficient local adsorption force during the attachment process of flat materials on complex curved surfaces, ensure that the material is tightly fitted on the surface of the special-shaped shell in the entire area, and improve the yield and molding accuracy of the curved surface attachment process.

[0056] See also Figure 1 and Figure 2 The present application further proposes that the flat material shaping mechanism also includes a positioning component 30, which is installed on the slider of the linear module 10 and is spaced apart from the forming component 20 for pre-positioning the flat material before forming.

[0057] In this embodiment, the positioning assembly 30 is a device that mechanically constrains the material to its spatial position, eliminating deviations during material transport. The positioning assembly 30 and the forming assembly 20 are arranged to maintain a specific spacing, which can be achieved through slider travel control. This spacing must be greater than the material length to prevent interference, ensuring that positioning and forming operations are performed separately.

[0058] Specifically, when the linear module 10 drives the slider, the positioning assembly 30 and the forming assembly 20 are synchronously moved to the processing station. After the material is conveyed to the positioning assembly 30, its centerline is aligned with the axis of the forming block 21. After positioning, the slider continues to drive the forming assembly 20 to move over the flat material for attachment and forming. During this time, the positioning assembly 30 remains stationary to avoid interfering with the forming process.

[0059] See also Figure 1 and Figure 2The present application further proposes that the positioning assembly 30 includes a positioning platform 31 and at least two side pushers 32. The positioning platform 31 is mounted on the slider of the linear module 10; the two side pushers 32 are mounted on the positioning platform 31 and are located on both sides of the positioning platform 31 to define the two sides of the flat material.

[0060] In this embodiment, the positioning platform 31 is a support structure for the flattened material. Specifically, it can be implemented using a metal plate or an engineering plastic plate. Its position is adjusted by the slider of the linear module 10, providing a stable placement base for the flattened material. The side thrusters 32 are devices used to constrain the flattened material on both sides. Specifically, they can be implemented using a mechanical structure that combines a pneumatic cylinder drive with an elastic buffer. The synchronized action of both sides creates a clamped position for the material, preventing lateral displacement during the molding process.

[0061] Specifically, after the positioning platform 31 moves to the preset position along with the slider of the linear module 10, the flat material is placed on the surface of the positioning platform 31. The side pushers 32 on both sides simultaneously push toward the material, and through the cooperation of the rigid pusher head 323 and the elastic member 322, a flexible clamping force is generated when contacting the material. The physical boundary formed by the pushers 323 on both sides confines the material to a predetermined area, ensuring that the center of the material is aligned with the contour of the forming block 21. When the material is pre-positioned, the side pusher 32 is reset to release the constraint, and the linear module 10 drives the positioning platform 31 and the forming assembly 20 to enter the subsequent forming process.

[0062] Compared with existing technologies, traditional manual positioning relies on visual adjustments by the operator, which is susceptible to material edge deformation or visual errors, leading to deviations in the attachment position. This solution, however, uses a mechanized side-pushing limiter structure to create a repeatable physical positioning reference on both sides of the material, eliminating the uncertainty caused by human intervention. This allows for precise pre-positioning of flat materials before forming, ensuring perfect alignment between the material center and the contour of the forming block 21, avoiding wrinkles or edge lift caused by material offset, and providing a stable initial position for subsequent vacuum adsorption or electrostatic forming processes.

[0063] In some specific embodiments, the positioning platform 31 is provided with vacuum adsorption holes or electrostatic adsorption devices for adsorbing and fixing the flat materials in the pre-positioning stage.

[0064] See also Figure 1 and Figure 2 The present application further proposes that each side push member 32 includes a side push cylinder 321 installed on the positioning platform 31, one end of the elastic member 322 is connected to the telescopic rod of the side push cylinder 321, and the push head 323 is connected to the other end of the elastic member 322 so that the push head 323 can move relative to the side push cylinder 321.

[0065] In this embodiment, the side push cylinder 321 refers to a power device for driving the push head 323 to move linearly, which can be implemented by a pneumatic linear actuator, and the extension and retraction of the telescopic rod are controlled by compressed air. The elastic member 322 refers to a connecting component with elastic deformation ability, which can be implemented by a coil spring or a rubber pad, and is used to provide a buffer and maintain a constant contact force when the push head 323 contacts the material. The push head 323 refers to the end component that directly contacts and pushes the flattened material, which can be made of metal or engineering plastic. The elastic member 322 forms a flexible connection with the side push cylinder 321 to compensate for the position deviation of the material.

[0066] Specifically, the telescopic rod of the side-thrust cylinder 321 is connected to the pusher head 323 via an elastic member 322. When the side-thrust cylinder 321 is activated, the telescopic rod pushes the elastic member 322 and the pusher head 323 toward the material. The elastic member 322 compresses and deforms upon contact with the material, absorbing impact forces caused by misaligned material position or uneven thickness while maintaining continuous contact pressure between the pusher head 323 and the material. The flexible support of the elastic member 322 allows the pusher head 323 to adaptively fine-tune its position, ensuring simultaneous and even pressure on both sides of the material, thus preventing material shifting or deformation caused by overloading on one side.

[0067] This solution introduces an elastic member 322 as an intermediate buffer element to enable the push head 323 to have adaptive adjustment capabilities, effectively avoiding damage to the surface or internal structure of the material due to rigid impact while ensuring positioning accuracy, eliminating the problem of uneven lateral pressure caused by material size error or positioning deviation, ensuring that the material remains accurately centered before entering the molding process, and avoiding surface scratches or structural deformation caused by hard contact between the push head 323 and the material, thereby improving the yield of the finished product.

[0068] See also Figure 1 and Figure 2 The present application further proposes that a flexible portion is provided on the side of the push head 323 facing away from the elastic member 322, and the flexible portion is used to contact and level the material.

[0069] The flexible part refers to the area where the push head 323 is in direct contact with the flat material. Specifically, it can be achieved by covering it with soft materials such as silicone, rubber or polyurethane. Its function is to buffer the contact pressure of the push head 323 on the flat material, avoid scratches or deformation of the material surface caused by rigid contact, and adapt to the edges of materials with different curved contours through material deformation.

[0070] Because the flexible portion is elastically deformable, it automatically adjusts its contact area to the curvature of the material surface during contact, preventing localized stress concentration and surface damage. For example, when the material edge has slight uneven structures, the flexible portion can locally compress and fill the gaps, ensuring stable contact between the pusher head 323 and the material. Furthermore, the elastic properties of the elastic member 322 allow the pusher head 323 to retract slightly after contact with the material, further reducing the risk of rigid impact.

[0071] Optionally, a sensor is provided on the push head 323 or the flexible portion for detecting whether there is contact with the flat material or detecting the contact force.

[0072] In another embodiment, it is further proposed that the forming workpiece 22 is an electrode body, which is located on the side of the forming block 21 facing away from the flat material. The electrode body is used to generate a strong electrostatic field after power is applied, so that the flat material is polarized and adheres to the forming block 21.

[0073] The term "electrode body" refers to a conductive component capable of generating an electrostatic field by applying a voltage. Specifically, this can be achieved using metal plates, conductive coatings, or graphene materials, with a potential difference formed by connecting to a high-voltage power supply. The side of the forming block 21 facing away from the flat material refers to the relative direction of the contact surface between the forming block 21 and the material. Specifically, positioning can be achieved through mechanical fixation or embedded installation to ensure that the electrode body and the forming block 21 maintain a preset distance. A strong electrostatic field refers to an electric field environment with an electric field strength sufficient to polarize non-conductive materials. This can be achieved by adjusting the voltage amplitude or the electrode spacing to redistribute the surface charge of the flat material and generate an electrostatic adsorption force.

[0074] Specifically, when energized, the electrode body forms a non-uniform electric field. When a flat material enters the electric field, its internal dielectric molecules polarize, generating induced charges opposite to the direction of the electric field. Because the forming block 21 is grounded or at a low potential, the polarized material is attracted to the surface of the forming block 21 by electrostatic attraction, naturally bending along the contour of the forming block 21. During this process, the electric field strength can be dynamically adjusted based on the material thickness or material properties. For example, the voltage can be appropriately increased for thin films with low dielectric constants.

[0075] Compared to existing technologies, electrostatic adsorption achieves uniform force across the entire surface without physical contact, making it particularly suitable for materials with microporous or breathable materials. Furthermore, the penetrating nature of the electrostatic field eliminates the need for complete contact between the material and the forming block 21 to generate effective adsorption, thus avoiding material stretching and deformation caused by mechanical pressure.

[0076] Optionally, the electrode body is a flat electrode or a curved electrode having a profile matching that of the forming block 21. The electrode body is connected to a high-voltage power supply, which can adjust the output voltage and / or current.

[0077] See also Figure 1 and Figure 2 The present application further proposes that the flat material shaping mechanism includes two forming components 20, the two forming components 20 are arranged at intervals, and each forming component 20 is used to shape a flat material.

[0078] The two forming components 20 maintain a non-overlapping spatial relationship in the direction of movement of the linear module 10, which can be achieved by horizontal parallel or vertical staggered methods to ensure that the two components do not interfere with each other during operation. The two forming components 20 are driven by the linear module 10 to work alternately. When the material picking nozzle 2 transfers the first type of flat material to the area of ​​​​one of the forming components 20, the component adheres and forms the material through vacuum adsorption or electrostatic action, while the other forming component 20 is in standby mode; after the first material is formed, the linear module 10 drives the other forming component 20 to move to the processing area to perform synchronous forming operations on the second type of material provided by the feeding nozzle 3. This alternating operation mechanism allows two different materials to be continuously processed in the same equipment. For example, in the manufacture of AR glasses temples, the curved surface forming requirements of optical films and metal shielding layers can be processed simultaneously.

[0079] In some specific embodiments, the forming blocks 21 of the two forming assemblies 20 can be configured with different radii of curvature, that is, the forming blocks 21 of the two forming assemblies 20 have different profiles, allowing them to form flat materials of different shapes. For example, one forming block 21 can be designed to accommodate the gradually curved surface on the inside of a temple, while the other forming block 21 can accommodate the stepped surface on the outside of the temple. The forming workpiece 22 can respectively utilize a vacuum generator and an electrode body, allowing one forming assembly 20 to utilize negative pressure adsorption when processing breathable materials, while the other forming assembly 20 utilizes electrostatic adsorption when processing non-breathable materials.

[0080] Compared to existing technologies, traditional equipment is limited to a single molding component 20. Processing multiple types of materials requires repeated mold changes or parameter adjustments, resulting in longer processing cycles and reduced positioning accuracy. This solution, through a dual-component parallel architecture, enables continuous processing of two materials without downtime for adjustments. For example, in an AR glasses production line, the molding processes of optical films and touch sensors can be completed simultaneously, eliminating equipment idleness due to process switching.

[0081] See also Figure 1 and Figure 2The present invention also provides a processing device comprising a base 1, a material retrieving nozzle 2, a material loading nozzle 3, and a flat material shaping mechanism. The material retrieving nozzle 2 is movably connected to the base 1 and is used to absorb the flat material to be formed; the material loading nozzle 3 is movably connected to the base 1 and spaced apart from the material retrieving nozzle 2 and is used to absorb the finished product after forming; the flat material shaping mechanism is mounted on the base 1 and is used to shape the flat material. The specific structure of the flat material shaping mechanism is similar to that of the above-mentioned embodiments. Since this processing device adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, and will not be detailed here.

[0082] The base 1 refers to the supporting structure of the main body of the supporting equipment, which is used to provide an installation reference and rigid support for other functional components. The material picking nozzle 2 refers to an end effector with an adsorption function, which can be implemented by a vacuum suction cup or an electromagnetic adsorption component combined with a robotic arm, and is used to transfer the material to be formed between the material storage area and the shaping station. The loading nozzle 3 refers to an adsorption device that is symmetrical in structure with the material picking nozzle 2, which can be implemented by a multi-degree-of-freedom robotic arm equipped with a vacuum generator, and is used to transfer the completed formed material to the unloading station. The flat material shaping mechanism refers to a composite device including a linear module 10 and a forming component 20, which is used to shape the flat material according to a preset curved surface contour. The material picking nozzle 2 and / or the loading nozzle 3 are end effectors of a multi-degree-of-freedom robotic arm. The processing equipment also includes a control system, which is used to coordinate and control the actions of the material picking nozzle 2, the loading nozzle 3, the linear module 10, the forming processing part 22 and the positioning component 30.

[0083] Specifically, the material retrieving nozzle 2, via a movable connection, moves within the planar space covered by the base 1, grabbing the material to be formed from the material storage area and transferring it to the station where the flattening and shaping mechanism is located. The flattening and shaping mechanism, driven by a linear module 10, moves the forming assembly 20, bringing the forming block 21 into contact with the material. Vacuum suction or electrostatic fields simultaneously adhere the material to the surface of the forming block 21, completing the three-dimensional shaping. After forming is complete, the loading nozzle 3 removes the finished product from the forming station and transfers it to the unloading area, achieving continuous, automated material processing from retrieving to forming and then unloading.

[0084] Compared with existing technologies, traditional processing equipment typically requires multiple independent devices to complete the material retrieving, forming, and unloading processes, resulting in the accumulation of multiple material positioning errors and a large equipment footprint. This solution integrates the retrieving, forming, and unloading functions into a single device, using a movable nozzle assembly and shaping mechanism to work together, reducing the number of material transfers and avoiding repeated positioning errors. In addition, the flattening mechanism can choose between vacuum adsorption and electrostatic field shaping according to different material characteristics, improving adaptability to different materials.

[0085] Through the above technical solution, this application realizes the full automation of the flat material processing process from material collection to forming and unloading, solving the problems of low efficiency and poor attachment accuracy of traditional manual operation. Through the coordinated control of the movable suction nozzle and the shaping mechanism, the material is ensured to maintain precise positioning during the transfer and forming process, avoiding wrinkles or offset defects caused by multiple manual interventions. The integrated design reduces the space occupied by the equipment and is compatible with multiple forming methods, meeting the needs of efficient attachment of complex curved shell substrates.

[0086] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformation made by utilizing the contents of the present invention's description and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
